Google Rips? Are they allowed?

[Retro64]

I was wondering if Rips from Google's HTML Easter eggs are allowed on the site. They aren't what most would consider video games but they have assets that can be ripped. Some of which are actaully stored internally as spriesheets. So are they allowed?

The Google Chrome T-Rex/Dinosaur Game has been ripped before, so if it has spritesheets and a playable interface in one form or another, I see no reason that they wouldn't be allowed.
